this is neither a geometric nor an arithmetic sequence
add 4, add 6, add 8
Since you have options, I would guess and check
n=2
2^2+2 =6
3(2)-1 = 5 no
(2+1) (2+2) =12 no
Choice A
Answer:
The answer is A. $1.35
Step-by-step explanation:
Two $10 bills are equal to $20.
Your change is $7.85
So if you subtract $7.85 from $20 you will come up with $12.15.
$12.15 is how much money you spend on mini burgers.
You can then divide how much money you spent with how many burgers you bought.
12.15 divided by 9 gives us 1.35. So each burger was $1.35.
Answer:
(a) 110 mm Hg
(b) 70 mm Hg
(c) 3/4 second
(d) see the attachment
Step-by-step explanation:
(a) The sine function has a maximum value of +1, so the maximum value of p is ...
pmax = 20·(+1) +90 = 20+90 = 110 . . . . . mm Hg
__
(b) The sine function has a minimum value of -1, so the minimum value of p is ...
pmin = 20·(-1) +90 = -20+90 = 70 . . . . . mm Hg
__
(c) The period of the sine function is 2π, so the value of t that makes the argument be 2π will be the period.
8π/3·t = 2π
t = 2π·3/(8π) = 3/4 . . . . . . multiply by the inverse of the coefficient of t
The period of her heartbeat cycle is 3/4 seconds.
__
(d) a graph is attached.
<EFD is also shown as e on the diagram. It is 90 degrees. <EFG is made up of the same two lines and is equal to 90 degrees (shown by the little box) so <EFD must be equivalent.
Let jena take x hours to mow the lawn on her own.- then we can write the equation
1/x + 1/4x = 1 / 44
44 + 11 = x
x = 55
x takes 55 hours to mow the lawn
